I'm trying to send request to a web server with a self-signed certificate (works fine on sites that aren't self-signed) and i keep getting the error:
SSLEOFERROR EOF occurred in violation of protocol
Conversely when using requests, the non-async http client for python, setting ssl_verify to false allows for a successful connection to the server. However the async http client, asks, lacks such a feature, i get the SSLEOFERROR.
Asks does allow accepting a customized ssl.SSLContext object, but after several attempts at this, and even adding the self-signed cert to my local keystore, nothing has resulted in a successful connection and the error stays the same.
import asks
import trio
from asks.sessions import Session
url_list = ['facebook.com', 'https://example.com']
results=[]
ssl_context=ssl.SSLContext()
ssl_context.verify_mode=ssl.CERT_NONE
ssl_context.check_hostname = False
async def grabber(s,url):
r=await s.get(path='/'+url)
results.append(r)
async def main(url_list)
s = Session(connections=2,ssl_context=ssl_context)
s.base_location='https://self-signedcert-site/'
s.endpoint='path/to/restapi'
async with trio.open_nursery() as n:
for url in url_list:
n.start_soon(grabber, s, url)
trio.run(main,url_list)
Results in the below (handtyped traceback.. not able to share/paste from the erroring machine) Begin SSLEOFERROR Traceback:

UPDATE I've identified some things.
If instead of using a session object I just use asks.get() i'm able to see granular changes in responses:
Asks Library
SSLEOFERROR: [Error fixed by using pip to install asks -- conda-forge is running 3 releases behind]
asks.get('https://url', auth=BasicAuth(usr_pw))
Invalid HTTP Response Error:
asks.get('https:url/rest/api/path',auth=BasicAuth(usr_pw))
Body of page is returned as expected:
asks.get('https://google.com')
Requests Library
Body of page is returned as expected:
requests.get('https://url', auth=HTTPBasicAuth=(usr_pw),verify=false)
Proper response returned from API as expected:
requests.get('https:url/rest/api/path', auth=HTTPBasicAuth=(usr_pw))
Considering there is another type of error I'm able to generate (invalid http response) I've added some more traceback for that Begin Invalid HTTP Response Traceback:
